Descripción
Minimum bias and underlying event data from the LHC and Tevatron have been used to tune the PYTHIA 6.4.28. We tune Multiple Parton Interaction (MPI) parameters including three Lambda parameters. It is shown that these tunings describe selected distributions quite well, especially pt distribution at three collision energies, 0.9 TeV , 1.9 TeV and 7 TeV provided that charge particles with pT > 500MeV are used. Results are presented using three types
of Parton Density Functions (PDFs) of proton : leading order (LO), modied leading order(LO*) and next-to-leading order (NLO). We found that all three types of PDFs can describe minimum bias and underlying event distributions equally well.
